The Chief of Staff is not typically considered a formal member of the Cabinet. However, they play a crucial role in the executive branch, serving as a primary advisor to the President and managing the White House staff and operations.
While the Cabinet is composed of the heads of the executive departments and other designated officials, the Chief of Staff often interacts regularly with Cabinet members and may even influence decisions at that level. Their position is more about facilitating communication and coordinating efforts among the various departments and advising the President directly.
In summary, although the Chief of Staff is not an official Cabinet member, their influence and involvement in governmental operations often make them a key player in the Cabinet’s overall functioning.
